That's incredibly audacious of you to give advice to others to time the stock price movement of GTAT.
People who believe in the GTAT story or are just starting to, should start building a position in it for LONG TERM growth; NOT try and DAY TRADE it.
Oh, lighten up. I'm only suggesting you're out for half a trading day. Since Nov 13th, the stock is up a total of 80 cents but there has been a $4 swing during that time. You can still be long on Mon and nobody will even know.
